I bought a launch-day 4S as an upgrade from my 3GS. I ended up exchanging that one due to a low-contrast, green-tinted screen. That kicked off a process of going through 3 more 4S phones, all of which had different issues (tinted screens, backlight uniformity problems, unable to hear other party on calls, earpiece static).
Given the problems I was having with the 4S, I decided that I would go 'cheap' and give the 4 a try instead. I was able to track down a new-old-stock 16 GB iPhone 4 (built Sep 2011) at the local Best Buy. Aside from a somewhat warm screen (looks ok at higher backlight settings), the phone feels much higher quality than the 4S units I have had. Everything just works, there is no static in the earpiece, it's put together properly, makes calls every time, and the screen has much better overall uniformity, clarity, and color saturation. It does seem to have the 'antennagate' issue (signal drops 3-4 bars) although this has yet to manifest as a problem for me in actual use.
Anyway, I think I am finally happy with a new phone but I am disappointed with Apple for making me go through this to find something reasonable. I hope this is just bump in the road and not indicative of their quality going forward.
